URGENT. Which is an exponential decay function? ANSWER GETS BRAINLIEST.

Mathematics
1 answer:
Leno4ka [110]3 years ago
7 0

Answer:

C

Step-by-step explanation:

For the first one, there is a ratio of change greater than one so that is exponential growth.

The second one has exponential decay but its x is negative making it actually exponential decay even if graphed.

The third one has positive growth over an interval of negative x, so in terms of  x there is exponential decay.

The fourth one is neither and if graphed is just points as there is a specific solution set.

In conclusion, the third is exponential decay!

Hope this helps :)

Answer:

  • diagram is below
  • 6, 11, 16, 21
  • s[n] = s[n-1] +5
  • 26, 31, 36

Step-by-step explanation:

a) See below for the next diagram in sequence.

__

b) The numbers of straws in each diagram are ...

  6, 11, 16, 21, ...

__

c) Each term is 5 more than the previous one, so the recursive rule for the number of straws is ...

  s[1] = 6

  s[n] = s[n-1] +5

__

d) The next three terms of the sequence are ...

  ..., 26, 31, 36, ...

If a triangle has side lengths of 5.6 yards, 7.1 yards, and x yards, find the range of possible values of x.
ANTONII [103]
Hi!

To find the range of possible values of x, we have to side 1 from side 2...

7.1 - 5.6 = 1.5

The smallest side x could be is 1.5.
Now add side 1 to side 2

7.1 + 5.6 = 12.7

The biggest side x could be is 12.7

So x could be anywhere from 1.5 to 12.7 (or, 1.5 < x < 12.7)

Hope this helps! :)

The width of a rectangle is 22 inches and the perimeter is at least 165 inches. what inequality could be used to find the minimu
Lera25 [3.4K]
The answer is D.

We know that a rectangle has two widths that are equal and two lengths that are equal. One width is 22, so the other one is also 22.

If you wanted to find the lengths, you would add both widths together (same as multiplying a width by two) and add that to the two lengths equaled to the perimeter.

So, 22 * 2 + 2x = perimeter of rectangle. We added all four sides together.

We know that the perimeter is at least 165, so 22 * 2 + 2x = 165. Here's the twist. They want the most minimum possible length. So, what answer choice gives you 165 or less for the most minimum or smallest length while still getting to 165?
That is D.
22 * 2 + 2x < = 165.
Hope this helped!

The cost in dollars (in dollars) of making x flip flops is represented by 40+4x. The cost (in dollars) of making x sandals is re
Anastasy [175]

Answer:

a. C = 12x + 110; b. $290

Step-by-step explanation:

a. The polynomial

 Let L = cost of flip-flops

and S = cost of sandals

Then

C =      L      +      S

  = 40 + 4x + 70 + 8x

  = 12x + 110

b. The cost

C = 12 × 15 + 110

  = 180 + 110

  = $290

The cost of making 15 flip-flops and 15 sandals is $290.

Identify all of the real fifth roots of 1024.
V125BC [204]

Answer:

Real fifth root of 1024 is 4.

Step-by-step explanation:

We have to find the value of real fifth root of 1024.

For this let fifth root of 1024 = x

Therefore x^{5} = 1024 = 4^{5}

Or x^{5}=4^{5}

Therefore x = 4

X= 4 is the right answer.
